I remember the Zenith Minisport, a DOS laptop with 2" floppies:
Don't think I ever saw one in real life, though.
Not sure any other computer ever used those media.
I own a number of Amstrad devices with 3" disks. But I don't think I
ever saw 3¼"!

This device was roundly mocked:
It's about the same thickness as the original hard-disk-based iPods,
which sold in the tens of millions and were regarded as a pinnacle of
miniaturisation. I think our list member Mr Corlett was the first to
note that, that I saw.
